MANUFACTURE OF PICTUBES.

To all whom it may concern:

Be it known that I, GEORGE R. BUTLER, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented new and useful Tmprovements in the Manufactureof Pictures, of which the following is a specification.

This invention relates to the art of picture making, and particularlypertains to puzzle pictures and means for producing 'the same.

It is an object of my invention to provide system of manufacturingComical or puzzle photographs or negatives; and to provide an apparatuswhereby said pictures are readily, easily, and cheaply produced.

The invention consists of the parts and the Construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawing, in which- Figure l is a centralvertical section of a device used to aid the manufacture of thepictures. Fig. 2 is a section on line 13-93 Fig. 1. Fig. 3 is a sectionon line y-y Fig. 1. Fig. 4 is a plan view of a puzzle picture negative.

It is desirable to provide a simple, efi'ective and inexpensive methodof manufacturing unique and puzzling images of various persons, objectsand animals. I have actually manufactured puzzle photographs by making adouble exposure on a single plate, utilizing a checkered stop.

In manufacturing puzzle pictures I employ a suitable frame A adapted tofit into a camera B of any preferred style. The frame A is provided witha suitable slide C which may be withdrawn in the well-known manner so asto eXposea sensitized medium, as plate 2. The plate 2 is removablymounted in a rotary holder or carrier 3 which is operable from the backof frame A, by a simple handle t. Interposed between the usual lens ofthe camera and the plate 2 is light stop 5 mounted slidably in groove 6of frame A. The stop 5 is partially opaque and partially transparent.Preferably this transparent portion is checkered as at a there beinghere shown six horizontal rows of quadrangles and five vertical rows.Their number, shape, and size are arbitrary.

The arrangement of the checkered sections is such that at one eXposureof the contiguous sensitive plate 2 just one-half Specificaton ofLetters Patent.

of its area is bared to the light rays, and this eXposed area will be aduplicate in form of the checkered step plate. Having exposed the plate,in part, if developed only a checkered image would appear over the plateand that portion which was covered by the opaque stop 5 would be clear.To complete the exposure of the entire area, the plate is turned up sidedown by means oli' the handle 4, and at the same time the stop member 5is shifted to the other side of the frame A, a distance just equal tothe width of a quadrangle a, whereby the opaque portion of the stop 5now covers that portion of the plate 'which was previously exposed, andthe transparent blocks register with the unexposed area of the plate 2.Now since the plate is turned upside down and the stop 5 has beenshifted sidewise and the camera Shutter again operated, the image formedon the plate will be readable opposite, or upside ,down to that firstformed, thus producing a picture covering the entire area of the platebut divided into a number of even sections, those being diagenal to eachother disclosing a normal image, all of one set of diagonal blocks beingnormal when the picture is held in one hand, while the remaining portionof the adjacent parallel block is invrted to the eye and only readablewhen the picture is turned end for end, see Fig. 4:.

Any suitable means may be employed for shifting the lattieed stop plate5 and an arm 7 of the rotatable carrier 3, by engaging a lug 8 of themember 5 will efi'ectually slide the stop 5 as the carrier 3 is justcompleting its turning motion.

Suitable steps 9 limit the movement of the carrier so that the checkeredareas of the plate to be eXposed will aline nicely.

Having thus described my invention, what I claim and desire to secure byLetters Patent is- 1. The method herein described of making photographs,said method consisting'n simultaneously exposing numerous isolatedportions of a sensitized medium to the action of light while stoppingthe light from the intermediate portions of said medium; then shiftingthe position of the medium; and then blocking out the light from theexposed portions of the medium and admitting light to the formeruneXposed intermediate portions of said medium.

2. The method herein described of making photographs, said methodconsisting in interposing a light-stop With transparent and opaqueportions between the light and the sensitized surface of thephotographic medium; then admitting light through the stop, Wherebyportions of the surface of the medium corresponding to the transparentportions of the stop are exposed; then re- Versing the mediumsubstantially end for end so that unexposed portions of the medium arebrought into register With transparent portions of the light-stop andeX- posed portions of the medium are brought into register With theopaque portions of said stop; and then making a second exposure.

3. The method of manufacturing photographs, which consists in firstexposing alternate sections only of a sensitized medium to the light,and then turning the medium end 'or end and exposing the remainingareas.

t. The method herein described of making photograghs said methodconsisting in exposing a sensitized medium in conjunction With a stophaving alternate transparent and opaque sections, and then reversing themedium and moving the stop to cover the previously exposed poi-tiene andexposing the remainder.

In testimony Whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
